The hem? is provied with e screwslot 31 by which 'iie boit is vpissed in position and! the crank shafteiiawn together. o I 1 To eek this boit and prevent the henger Thecranks .are

' washers. Adjustment in this from workinlgv loose, I provide anexteriorly threaded dis or nut 32, which engages the threads 25 andbears against the outer edge of the head 29 therebv acting as a locknut, in this mannereifectively holding the bolt against turning. 0n thethreaded end of bolt 28 an additional lock is provided and also a finishsimilar to the opposite side, by means of the conical nut 33, this -nutengaging the threads 30 which project within the.

recess 26.

The sleeves 19 are held iny contact with the spacing sleeve and spacedVon the crank shaft by means of the washers 34. These washers have aconical shape so that when the hub is assembled the inner edge bearsagainst the outer face of the sleeve 19 while the outer edgerestsagainst the shoulder between hub and shaft. In this manner any variationbetween the outer surfaces of the two members 10 istaken up by the sring of the orm of bearing is secured by turning one of the members 5 onthe screw threads 8, the sleeves 19 being self centering between theball races 7, the same is maintained by clamping the hanger' socket 1vtight upon tie extension 6 by means of the balls 5.

In the modified form shown in Fig. 2 the crank shaft is constructed inthe exact manner heretofore described, but the bearings are held inplace thereon in a dierent manner. In this form sleeves 35 are rovidedwhich fit closely on the hanger sha t 15 and are centered thereon bymeans of the conical washers 34. Each of these sleeves are provided witha reduced portion 36, which is exteriorl'y threaded and a furtherreduced portion 37 leaving the shoulder between the attcr and thethreaded ortion 36. Interposed between this shoul er on two members is asleeve 38 whereby the two members 35 are held in spaced relation.V Thehub end of members 35 are provided with ball race members 39 and onthreaded portion 36 are rings 40 provided with a similar andsymmetrically disposed race member. Each ring has holes 41 by which thesame is turned through a suitable wrench by means of lock ring 42similarly provided with wrench openings. 'Outside of member 35 andfitting around the same is member 43 having the race member 44 givingtwo points of contact. These members are shouldered as at 45 and 46, theformer serving as a stop for the sleeve 46 whereas the latter furnishesan abutment for the hanger socket 1. l

From the above description it will be apparent that I have provided adevice which eiectively accomplishes the objects set forth at thebeginning of the specification as by the use of the inclined faced jawclutch coupled with the manner of holdin the same in contact, there isformed a cran hanger,

and is locked in position.

assises the two sides of which are rigidly connected together and yetcapable of ad)u'stment-iff wear takes place.

Also the manner of adjustin the bearings' is such that the pressure on aball races is equal and the adjustment once Lmadeis effectively held.

What I claim as new and wish to cover by* Letters `Patent isz- 1. Acrank hanger comprising a' socket,

having an axial slit, ball` race members ,in said socket and adapted tobe clamped against rotation, a sleeve in threadedengage mentv with theinner endof the race members whereby said race mem ers are held in ad-ljustable spaced reiation, a pair of c s having shafts revolubly, mountedin said socket, ball race membersxcarried by said shafts and coactingwithlthe bali race mem'- bers held on'said socket,la sleeve surroundingsaid crank shafts and holding said last` mentioned race membersin'spaced relation,

, intermeshing clutch Iteeth 4formed on the inklner ends of said crankshafts, a iianged hub gli the outer ends of said crank shaft, and aspring washer abuttin against said flange and said ball races on saidcrankashafts.

f A 2. A crank hanger comprising, a. hanger socket, a pair of ball racemembers adapted to be clamped in said socket, a'two piece crank shafthaving enlarged hubs on the outer ends, a pair of ball race memberscarried bysaid shaft, sleeves coacting with each of said pairs of ballrace the same in spaced relation,

one ef said sleeves being 1n threaded engagementI with one of said pairsof ball race members, annular washers having faces inclined to theiraxis interposed between said'enlarged hubs and the ball race members onsaid shafts and means for drawing said shafts together and thereby alsodamping said last mentioned pair of ball race members.

3. Acrankhanger comprising a sccket,ball race members adjustably heldtherein, a pair of cranks having shafts extending into said socket, saidshafts having complementary interengaged clutch teeth on theircontiguous ends, all race members carried by said shafts and coperatingwith the race mem#y bers of said socket, a headed bolt extendinglongitudinally through said shafts, a nut engaging said bolt, saidcranks havin recesses to receive said nut and the head o? said bolt, anda locking device in one of said recesses engaging the head of the bolt.

4. A crank hanger comprisin a socket,

members tc hold ball race members adj ustably hel therein, a

'mg a conical head fitting in the recess in one In testimony whereof Iafx my signature of the cranks, a comcal nut Wlthm the recess 1npresence of two W1tnesses.
